European adolescents (n = 1481, 12.5–17.5 years) were measured. Intake was assessed via two non-consecutive 24-h dietary recalls. Lower and upper limbs muscular fitness was assessed by standing long jump and handgrip strength tests, respectively. Cardiorespiratory fitness was assessed by the 20-m shuttle run test. Physical activity was objectively measured. Socioeconomic status was obtained via questionnaires. Lower limbs muscular fitness seems to be positively associated with tryptophan, histidine and methionine intake in boys, regardless of centre, age, socioeconomic status, physical activity and total energy intake (model 1). However, these associations disappeared once carbohydrates intake was controlled for (model 2). In girls, only proline intake seems to be positively associated with lower limbs muscular fitness (model 2) while cardiorespiratory fitness seems to be positively associated with leucine (model 1) and proline intake (models 1 and 2). None of the observed significant associations remained significant once multiple testing was controlled for. In conclusion, we failed to detect any associations between any of the evaluated AAs and physical fitness after taking into account the effect of multiple testing. 000060969 536__ $$9info:eu-repo/grantAgreement/EUR/FP6/FOOD-CT-2005-007034 000060969 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000060969 590__ $$a2.906$$b2017 000060969 591__ $$aBIOCHEMISTRY & MOLECULAR BIOLOGY$$b148 / 292 = 0.507$$c2017$$dQ3$$eT2 000060969 592__ $$a1.135$$b2017 000060969 593__ $$aClinical Biochemistry$$c2017$$dQ1 000060969 593__ $$aOrganic Chemistry$$c2017$$dQ1 000060969 593__ $$aBiochemistry$$c2017$$dQ2 000060969 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000060969 700__ $$aBel-Serrat, S. 000060969 700__ $$aCuenca-Garcia, M. 000060969 700__ $$aGonzalez-Gross, M. 000060969 700__ $$aPedrero-Chamizo, R. 000060969 700__ $$aManios, Y. 000060969 700__ $$aMarcos, A. 000060969 700__ $$aMolnar, D. 000060969 700__ $$aWidhalm, K. 000060969 700__ $$aPolito, A. 000060969 700__ $$aVanhelst, J. 000060969 700__ $$aHagströmer, M. 000060969 700__ $$aSjöström, M. 000060969 700__ $$aKafatos, A. 000060969 700__ $$ade Henauw, S. 000060969 700__ $$aGutierrez, Á. 000060969 700__ $$aCastillo, M.
